Description

Technical Field

[0001] This invention relates to the field of linear drainage channel technology, specifically to a stainless steel linear drainage channel with adjustable gaps and its adjustment method. Background Technology

[0002] Straight drainage ditches installed outdoors in parks, scenic areas, and residential communities typically consist of an underground drainage ditch, a metal framework supporting the ditch, and stone paving tiles adhered to the metal framework with cement mortar. A straight drainage channel is positioned directly above the drainage ditch, between adjacent stone paving tiles. During rain, rainwater flows through the openings in the straight drainage channel into the drainage ditch and is then drained away.

[0003] Chinese patent CN202120152330.8 discloses an easily detachable linear drainage ditch structure, including a drainage ditch body installed in the ground, a drainage channel frame located above the drainage ditch body, a linear drainage channel set on the drainage channel frame, and stone floor tiles set on the drainage channel frame. A metal keel is pre-embedded in the drainage ditch body, and a horizontal steel plate is set at the top of the metal keel, located at the upper end of the drainage ditch body. The drainage channel frame is welded to the steel plate. A protrusion is provided on the back of the stone floor tile, and a limiting opening is provided on the drainage channel frame corresponding to the shape of the protrusion, with the protrusion located in the limiting opening. This utility model has a more reasonable structure; it does not require adhesive bonding, is easy to construct, facilitates quick installation, has low installation costs, and allows for easy removal of the stone floor tiles during dredging, enabling dredging operations from the limiting opening, making the dredging operation easy and less likely to damage the stone floor tiles.

[0004] In actual use, the aforementioned patent has fixed drainage gaps, which can easily cause blockages when there is a lot of debris during drainage, affecting the drainage effect. In addition, there is no filtration mechanism, and impurities during the drainage process can easily cause blockages in the drainage gaps. Therefore, it does not meet the existing needs. In response, we propose a linear drainage channel with adjustable stainless steel gaps and its adjustment method. Summary of the Invention

[0015] Preferably, the adjustment mechanism includes a first rack, a limiting plate, an adjustment port, a gear, a second rack, and a rotating shaft. The bottom of the adjustment port is fixed with a rotating shaft, and a gear is fixed on the rotating shaft. The first rack and the second rack are respectively meshed on both sides of the gear. The tail ends of the first rack and the second rack are both fixed with limiting plates.

[0016] Preferably, the first rack is fixed to the first mounting plate, the second rack is fixed to the second mounting plate, the adjustment port is installed in the mounting groove, the bottom of the rotating shaft passes through the gear and is mounted at the bottom of the mounting cavity, and the first rack and the second rack move in opposite directions.

[0017] A method for adjusting a stainless steel linear drainage channel with adjustable gaps includes the following steps:

[0018] Step 1: Install the drainage channel. Install the metal keel inside the cavity of the drainage channel body to support the drainage channel body. Set two steel plates with a certain gap between them. Weld the mounting frame to the upper surface of the drainage channel body and weld it to the steel plate.

Then, adjust the port to drive the rotating shaft to rotate, so that the first rack and the second rack move along the gear. Adjust the distance between the first mounting plate and the second mounting plate, and move the two long strips inside the outer tube to adjust the drainage gap.

[0020] Step 3: When impurities on the filter plate need to be cleaned, pull the hook upwards to pull the connecting shaft and move the filter plate to the outside of the drainage gap, so that the two filter plates are in an inverted triangle shape. Maintenance personnel can then clean the surface of the filter plates.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The present invention uses a rotating shaft to move the first and second racks along the gear, adjusting the distance between the first and second mounting plates, thereby moving the two long strips inside the outer sleeve to adjust the drainage gap. The drainage gap can be adjusted according to the drainage needs, ensuring the drainage effect and improving the practicality of the device.

[0023] 2. This invention uses a filter plate placed between two long strips to block impurities passing through the drainage gap. This not only prevents impurities from clogging the drainage gap but also prevents them from entering the drainage ditch and causing blockage. Adjusting the drainage gap allows the filter plate to adjust accordingly without affecting its filtration effect. By pulling the hook upwards, the filter plate can be pulled outside the drainage gap, making it easy for maintenance personnel to clean. This eliminates the need for frequent filter plate replacements, saving costs and simplifying the operation. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To address the issue that existing drainage gaps are fixed, and that excessive debris can easily cause blockages during drainage, thus affecting drainage efficiency, please refer to [link to relevant documentation]. Figures 1-6 This embodiment provides the following technical solution:

[0035] A stainless steel adjustable-gap linear drainage channel includes a drainage channel body 1, stone floor tiles 2, and a metal keel 5. The drainage channel body 1 has a cavity 4 inside, and the metal keel 5 for support is installed in the cavity 4. A steel plate 6 is welded to the upper surface of the metal keel 5, and the stone floor tiles 2 are laid on the upper surface of the steel plate 6.

[0036] It also includes a frame 3, which is set on the upper surface of the drainage ditch body 1 and fixed to the steel plate 6 by welding.

[0037] It also includes a connecting structure 7, which is disposed inside the mounting frame 3 and welded and fixed to the outer sleeve 10. The connecting structure 7 is fixed on the adjusting mechanism 9, and the adjusting mechanism 9 is fixed inside the mounting frame 3.

[0038] It also includes a filter mechanism 8, which is rotatably mounted between two long strip plates 11. Two long strip plates 11 are provided, and the two long strip plates 11 are parallel to each other to form a drainage gap. The long strip plates 11 are movably mounted inside the outer sleeve 10, and the outer sleeve 10 is welded to the inner side of the steel plate 6. The mounting frame 3 includes a fixing frame 31, a slot 32, a mounting groove 33, a protective cover 34, and a mounting cavity 35. The upper surface of the fixing frame 31 has a mounting groove 33, and the surface of the mounting groove 33 is movably mounted with the protective cover 34 through a fixing shaft. The inner side of the fixing frame 31 has a slot 32, and the interior of the fixing frame 31 has a mounting cavity 35. The protective cover 34 is fixed by fixing screws. The connecting structure 7 includes a first mounting plate 71, a first connecting plate 72, and a second mounting plate 73. A first baffle 74 and a second baffle 75 are fixed to the outer side of the first mounting plate 71. A first connecting plate 72 is connected to the end of the first mounting plate 71 away from the second baffle 75. The end of the first connecting plate 72 away from the first mounting plate 71 is fixed to the second mounting plate 73. A first baffle 74 is fixed to the outer side of the second mounting plate 73. The first baffle 74 and the second baffle 75 are used to seal the slot 32, preventing debris from entering the mounting cavity 35 and protecting the adjustment mechanism 9 inside the mounting cavity 35. The first baffle 74 and the second baffle 75 are movably installed on the inner wall of the mounting cavity 35. A slot is provided on the first mounting plate 71, and the first connecting plate 72 is movably installed in the slot. An opening 76 is provided on the second mounting plate 73 to facilitate the... The passage of rack 91 ensures the normal operation of the adjusting mechanism 9, facilitating the adjustment of the distance between the two long strip plates 11. Simultaneously, it blocks the slot 32, preventing debris from entering and affecting the gap adjustment, which would also make cleaning difficult. The adjusting mechanism 9 includes a first rack 91, a limiting plate 92, an adjusting port 93, a gear 94, a second rack 95, and a rotating shaft 96. The rotating shaft 96 is fixed to the bottom of the adjusting port 93, and the gear 94 is fixed to the rotating shaft 96.

Limiting plates 92 are fixed to the tail ends of both the first rack 91 and the second rack 95, limiting their movement and preventing them from disengaging. The gear 94 affects the adjustment of the gap. By rotating the adjustment port 93, the rotating shaft 96 is driven to rotate, which in turn causes the first rack 91 and the second rack 95 to move along the gear 94, adjusting the distance between the first mounting plate 71 and the second mounting plate 73. This moves the two long strip plates 11 into the outer sleeve 10, achieving the purpose of adjusting the drainage gap. The drainage gap can be adjusted according to the drainage needs, ensuring the drainage effect and improving the practicality of the device. The first rack 91 is fixed on the first mounting plate 71, and the second rack 95 is fixed on the second mounting plate 73. The adjustment port 93 is installed in the mounting groove 33. The bottom of the rotating shaft 96 passes through the gear 94 and is rotatably installed at the bottom of the mounting cavity 35. The first rack 91 and the second rack 95 move in opposite directions.

[0039] To address the issue of existing drainage gaps lacking filters, which easily clog the gaps due to impurities during drainage, please refer to [the relevant documentation / reference]. Figures 7-8 This embodiment provides the following technical solution:

[0040] The filtration mechanism 8 includes a filter plate 81, a movable partition 82, a mounting shaft 83, a connecting shaft 84, and a hook 85. The movable partition 82 is fixed to the inner sidewalls of two long strip plates 11. The filter plate 81 is movably mounted on the movable partition 82 via the mounting shaft 83. Two filter plates 81 are provided, and the bottoms of the two filter plates 81 are movably mounted together via the connecting shaft 84. The tail end of the connecting shaft 84 is fixed with a hook 85. The filter plates 81 block impurities passing through the drainage gaps, preventing impurities from clogging the drainage gaps and preventing impurities from entering the drainage ditch 1 through the drainage gaps and causing blockage of the drainage ditch 1. The movable partition 82 includes a first partition 821, a second connecting plate 822, and a second partition 823. The first partition 821 and the second partition 823 are respectively fixed to the inner sidewalls of the two long strip plates 11. On the side wall, a slot is provided on the first partition 821, and a second connecting plate 822 is movably installed in the slot. The end of the second connecting plate 822 away from the slot is fixed on the second partition 823. The second connecting plate 822 moves in the slot, thereby adjusting the overall width of the movable partition 82. When the second connecting plate 822 moves in the slot, it pulls the filter plate 81 to rotate along the mounting shaft 83. While adjusting the drainage gap, the filter plate 81 is adjusted accordingly without affecting the filtration effect of the filter plate 81. When the impurities on the filter plate 81 need to be cleaned, the hook 85 is pulled upward to pull the connecting shaft 84, pulling the filter plate 81 to the outside of the drainage gap. At this time, the two filter plates 81 are in an inverted triangle state, which makes it convenient for maintenance personnel to clean the filter plates 81. The filter plates 81 do not need to be replaced frequently, saving costs and simplifying the operation.

[0041] Specifically, based on the aforementioned adjustable stainless steel linear drainage channel, this embodiment proposes a method for adjusting the adjustable stainless steel linear drainage channel, including the following steps:

[0042] Step 1: Install the drainage channel. Install the metal keel 5 inside the cavity 4 of the drainage ditch body 1 to support the drainage ditch body 1, improving its strength and service life. Then, weld the steel plate 6 to the upper surface of the drainage ditch body 1. Two steel plates 6 are used, with a certain gap between them to facilitate drainage. Weld the mounting frame 3 to the upper surface of the drainage ditch body 1 and weld it to the steel plate 6 to improve the installation's firmness. Then, weld the outer sleeve 10 to the inside of the steel plate 6. The long strip 11 is fixed to the first mounting plate 71 and the second mounting plate 73 to form a drainage gap. The long strip 11 can move inside the outer sleeve 10, facilitating the adjustment of the drainage gap.

[0043] Step 2: Adjust the drainage gap according to the drainage requirements. Open the fixing screws and lift the protective cover 34. Then, the adjusting port 93 drives the rotating shaft 96 to rotate, so that the first rack 91 and the second rack 95 move along the gear 94. Since the first rack 91 and the second rack 95 move in opposite directions, the first mounting plate 71 and the second mounting plate 73 move in opposite directions, thereby moving the two long strip plates 11 into the outer sleeve 10, so as to adjust the drainage gap and make the drainage gap adapt to the drainage requirements, thus ensuring the drainage effect.

[0044] Step 3: When impurities on filter plate 81 need to be cleaned, pull hook 85 upward to pull connecting shaft 84, pulling filter plate 81 to the outside of drainage gap, so that the two filter plates 81 are in an inverted triangle state. Maintenance personnel can then clean the surface of filter plate 81. This not only avoids impurities clogging filter plate 81, but also makes it convenient for maintenance personnel to clean filter plate 81. It eliminates the need for frequent replacement of filter plate 81, saves costs, and is simple to operate.
